Gordon said: Primare’s SC15 Prisma streaming preamplifier is a beautifully built, fine-sounding component that can accommodate a plethora of digital sources as well as high-quality streaming from mobile devices, and its small footprint makes it very attractive for use in multi-purpose living spaces.

Diego said: All of this functionality comes in a package that delivers on Moon’s promise of superlative sound and build quality, and is warranted for ten years -- exceptionally long in high-end audio. Printed on the 390’s carton is a promise of “The Performance of a Lifetime,” and I can’t disagree.

Howard said: Theoretica’s BACCH-SP technology, which I highly recommend, is at the bleeding edge of IXTC’s continuing evolution, and so effective that it has convinced me that the future of audio playback is not in incremental advancements in electrical circuit design or the operation of mechanical hardware, but in DSP technologies that fool the brain in increasingly sophisticated ways.

Garrett said: I found in it virtually no faults to speak of -- its prowess was evident with all genres of music, and its built-in phono stage was of reference level and the equal of almost any other standalone phono stage other than the most extreme luxury models I’ve heard.
